Full Idea
Since the end of the whole city is a single end, it is evident that education too must be one and the same for all, and that its supervision must be communal, not private as it is at present.
Gist of Idea
A city has a single end, so education must focus on that, and be communal, not private

A Reaction
But the end of the city is for all individual citizens to flourish, not for the group to flourish. So presumably education must be tuned to individual capacities and needs, and not just focus on some communal good.
